檢查fstab文件爲了

Question

我想寫一個python腳本來檢查，如果「父」安裝之前「孩子」點 存在掛載點，例如 /mnt前應/mnt/mount1

這是我已經寫了這麼遠

#!/usr/bin/python 

for line in open("/etc/fstab", "r"): 
    line = line.strip() 
    if line == "": 
    continue 

    lintyp = linetype(line) 
    if lintyp >= type: 
    type = lintyp 

要麼蟒蛇甚至慶典

Answer 1

妍可以使用fstab模塊，我用StringIO.StringIO更換open('/etc/fstab', 'r')：

import StringIO 
from fstab import Fstab 

s = content = """\ 
# this is a comment, followed by an empty line 
# the next line is a syntax error 
yo! 
#UUID="2b0ab63e-fd1b-4d7a-b021-3827b4aa4c8b" /media/hda3 ext3 defaults 0 2 
/dev/hda2 /boot ext3 defaults 0 2 
/dev/hda1/ext3 defaults,errors=remount-ro 0 1 
""" 

fstab = Fstab() 
#fstab.read(open('/etc/fstab', 'r')) 
fstab.read(StringIO.StringIO(content)) 

output = [] 
_fs = [] 
for line in fstab.lines: 
    if line.has_filesystem(): 
     _fs.append(line.raw) 
    else: 
     output.append(line.raw) 

_fs = sorted(_fs) 
output.extend(_fs) 


output = '\n'.join(line for line in output) 
print output 
#You have just to write to '/etc/fstab'
